Doctor Whois not immune to certain tropes, as admitted by the Ninth Doctor 20 years ago.Doctor Who’smodern-erarevival reinvented the show in 2005, introducing an era that changed people’s perceptions of the series and featuring a variety of new elements. This includesChristopher Eccleston as the Ninth Doctorand Billie Piper as his trusted companion, Rose Tyler.

Another important new element was theDoctor’s psychic paper inDoctor Who. Appearing as a small piece of blank paper, the psychic paper convinces the target to see whatever its user intends. As a result, the Doctor often uses it as a form of identification, although it has been used for many purposes, including as a credit card. While it has been a part of the Doctor’s arsenal since his second variation,the psychic paper only makes a prominent on-screen appearance after the Ninth Doctor uses it in “The End of the World.”

This David Tennant Doctor Who Episode Could Have Been A Classic, But The Villain Ruined It

David Tennant’s era as the Tenth Doctor boasts some truly excellent episodes, but other installments fall victim to being overly ambitious.

The prominent appearance of the psychic paper in thisDoctor Whoepisodesets up its reoccurring usage throughout the rest of the modern era of the show because of how useful it is. The psychic paper is essentially a “get out of jail free card" that enables the Doctor to skip past the need to convince his target that he should be allowed access to somewhere.The Ninth Doctor’s comment that the paper “saves a lot of time” is a meta line to the audienceacknowledging that the psychic paper will continue to be used as a plot device.

Doctor Who Without The Psychic Paper Would Be A Lot Less Interesting

The Psychic Paper Does Save A Lot Of Time

While theDoctor is mostly known for his sonic screwdriver, the psychic paper is a tool that is just as important to his time-traveling lifestyle as, without it,Doctor Whowould be a much more tiring show. As one of the smartest and most well-equipped people in the universe, the Doctor must be granted unprecedented access to certain situations, as his involvement could potentially save the day. However,security clearances, exclusive guest lists, and people’s general mistrust all stand in the way of accessand would present a time-consuming challenge if the Doctor didn’t have his psychic paper.

The Doctor needs to be specific about what they want the psychic paper to display as a broad idea, like a “worst nightmare,” could return something unexpected.

Instead of having to convince everyone that he should be allowed to do something, the Doctor uses the psychic paper to shut down arguments and save a lot of time. The use of seemingly “correct” credentials also keeps the Doctor from getting captured so much, hindering him in his mission, and allowing the story to focus on the main action. While thismodern-eraDoctor Whoplot device is often inconsistent with its rules, the showacknowledges its reliance on the way-too-convenient trope from the psychic paper’s first appearance and therefore, sometimes throws curveballs to keep things interesting inDoctor Who.
